Do we need to use <ul><li>...</li></ul> when we are using <nav>...</nav> tags?

Not sure what your question is exactly. Your wording is very hard to understand what exactly you are trying to accomplish, but when making a nav, do it this way:

<nav>
  <ul>
     <li>Item 1</li>
     <li>Item 2</li>
     <li>Item 3</li>
     ......
  </ul>
</nav>

Nothing redundant about that, and there is really no other way to make a proper nav menu with more than one item. This is semantically correct, easy to decipher what is going on, and no reason not to do it utilizing best practices...

Hi,

Thank you for your reply. I am sorry for the ambiquity in the wording.

I was trying to understand the utility of the nav tag, and (wrongly) thought that this element allows users to make menu items w/o the use of the ul tag.

I now understand that it is mainly for semantics.

Why do we need to us <ul> for navigation?
